' In Great Britain September 26, 1933 p 7 Claims. The present inventionrelates to new and useful improvements in telephone sets or to attach-:.ments or accessories therefor of the type in 15 ceiver to an operativeposition for the transmission of a message.

A further object of the invention is to provide a device of the abovecharacter wherein there is provided a movable platform and means con- 20necting said platform with the receiver and the hook switch whereby uponthe movement of said platform, the required electric circuit isestablished and the receiver is moved to an operative position for thetransmission of a message. 25 The above and other objects of the;invention will in part be obvious and will be hereinafter morefullyvpointed out.

In the drawing:

Fig. 1 is a perspective view of a telephone set I 30 of the typeembodying a receiver and a mouth,- piece as separate elements andshowing the construction of the present invention applied there- Fig. 2is a side elevation. of a telephone set em- 35 bodying a receiver and amouthpiece as a single unit and showing the construction of the presentinvention as applied. thereto.

Figs. 3, 4 and 5 are detailed views showing modifications of theoperating platform and the 40 manner in which they are displaceable.

Referring more in detail to the accompanying drawing and particularly toFig. 1, the mouthpiece III is connected to the usual standard II whichis mounted on a base plate I2. Extending 45 from the standard II is theusual hook switch I 3 which establishes the necessary electric circuit.A platform It has side arms Ha which are pivotally mounted on the baseplate I2 as at iii. A bracket member I6 is suitably secured to I50 thestandard II and has an outwardly projecting portion I60. to whichispivotally mounted at ll a rocker a'rm I8. The arms Illa of theplatform ll are suitably connected to one end of the rocker arm I8. Inthis particular instance, the arms 65 I la are connected by a forkedlink I9 which in turn is connected to a second link 20 pivotallyconnected as at 2I to the rocker arm I8. The receiver 22 is carried by aspring clip 23 which is adjustably mounted on a post 24. The post 24fits within asleeve 25 and is adjustable verti- 5 cally therein and isheld in position by a knurled nut 26. The sleeve 25 is pivotally mountedfor swinging movement on an arm 21 and is held in position by a wing nut28. The arm 21 is pivotally mounted for. horizontal turning movement onthe rocker arm Hi. It will thus be seen that K the receiver 22 may beadjusted relative to the rocker arm l8 and is capable of a universalmovement relative thereto.

As shown in Fig. 1, the rocker arm I8 is disposed over the hook I3 sothat in this position the hook switch I3 is depressed and the circuit isclosed. A spring 29 serves to normally hold the platform It in a raisedposition although the weight of the receiver on the rocker arm I8 mayserve this purpose. It will be noted that when the platform I4 isdepressed, the connecting links I9 and 20 will move downwardlythus'causing the rockerarm ill to move in a clockwise direction aboutits pivot I1 so that the hook switch will be permitted to ascend andthus establish the required electric circuit and at the same time thereceiver 22 will be moved in a clockwise direction to an operativeposition relative to the mouthpiece I I] so that the operator does nctneed 30 to hold the receiver at any time after it has once beenadjusted.

-A pivoted catch 30 on the base l2 may be employed for holding theplatform It in its depressed position with the telephone set inanoperative position with the circuit established. If it is desired topermit an operator at an exchange or some other remote point to controlthe set, an electromagnet 3| is provided which, when energized, exerts apull on the catch Slim 9. direction toward the platform I4 so as to holdthe same in its depressed position. Should the circuit be broken by theoperator, the magnet will be de-energized, and the spring catch 30 willmove out of contact with the platform so as to release it.

A sign 32 is mounted on the base I2 and is normally disposed beneath theplatform I4, but when the platform is depressed, the sign is disposedabove the same so as to indicate to the observer that the set is in aposition consistent with use. A writing pad or the like, Mb, may bemounted on the platform I4.

Referring to Fig. 2, there is shown a telephone set of the type whereinthe mouthpiece and rcceiver are a single unit. In this case, theplatform I is pivoted to the base l2 in a manner similar to that shownin Fig. 1'. A bracket lGa f has pivotally mounted thereon a rocker armI811 5 which is connected by a link 20a to the platform II. The rockerarm Ila has mounted thereon for adjustment a sleeve 25a. in which ismounted a post 24a which may be adjusted vertically and held by aknurled nut 26a. The post 24a carries a spring clip 23a in which themouthpiece Ma of the telephone set is mounted. The rocker arm Ilaextends over the hook switch [311 in a manner similar to that shown inFig. 1. When the parts are inthe position shown in Fig. 2, the

- hook switch I 3a is depressed. When the platform I 4 is moveddownwardly, the connecting link a will cause the rocker arm lfla to movein clockwise direction, thus releasing the hook switch Ba and moving thereceiver or ear piece 22a to an oper- 20 ative position.

In Fig. 3, the depression of the platform ll may be through the mediumof a foot rest (not shown) which is connected thereto by a link 33. Thislink 33 may be formed as an extension of the link 19 or the link 20a.

' In Fig. 4, the platform I 4 is pivotally connected to a link 34 whichis pivoted at one end to the base l2 and intermediate its ends to thelink I! or 20a. In this form, the depression of the platform I 4 causesthe same to slide longitudinally of the base plate It.

In Fig. 5, the platform I 4 is shown mounted on a pair of links 35, oneof which may be connected to the link I! or Me. In this form, the

5 platform I! remains parallel to the base l2 while it is beingdepressed.

It will be readily understood from the foregoing description, that thepresent invention provides an improved telephone set or anattachmenttherefor which operates to establish the required circuit andat thesame time to move the receiver into an. operative position so thatthe operator need not hold the receiver at any time, thus allowing freeuse of the hands for taking notes or the like.
